Official Title: Photographic Analysis Of Soft Tissue Facial Profile In Patients With Class II Malocclusion
Brief Summary:
The present day social setup considers facial charisma as an important physical characteristic. The facial characteristics of an individual are measured through anthropometry, photogrammetry, computer imaging and cephalometric radiographs. Cephalometric radiographs offer significant diagnostic information regarding the association between the dental and skeletal structures. By means of photogrammetric measurements, a fresh diagnostic resource is accessible to the orthodontist which permits an intangible, radiation free attainment of measure points of soft tissue with no instrumental expense and radiation to the patient.
Orthodontic patients range from adolescents to senior citizens and originate from an assortment of populations, thus an extensive series of representative norms will be ideal. Knowledge of the normal dentofacial outline of every group will make certain better success of treatment to set up the best possible facial agreement. Hence, it is extremely important to assess the soft tissue profile of a patient as it is one of the most vital components of orthodontic diagnosis and treatment planning.
The purpose of the present study is to evaluate the photographic characteristics of soft tissue facial profile of patients with class II malocclusion as ethnic differences have been found to be reported in the literature. It is hypothesized that soft tissue facial characteristics on lateral profile photographs and lateral cephalometric radiographs in a sample of local population with class II malocclusion are closely related.
Detailed Summary:
The goal of orthodontic treatment planning is to achieve facial synchronization by an esthetically pleasing face.It was a common idea in orthodontic treatment planning that soft tissue enhancement would follow the hard tissues, but this did not always happen.The reaction of soft tissue to hard tissue movement is not found to be consistent.With the emergence of a new paradigm in orthodontic diagnosis and treatment planning, greater emphasis has been placed on the relationships of soft tissues and lesser emphasis on the treatment of malocclusion. During the last few years, diagnosis and treatment planning in orthodontics has been reallocated in the direction of facial planning. Formerly, a lot of consideration was placed on the dental and skeletal components but now greater thought is paid to the soft tissue components. The purpose of treatment in the new paradigm is to place the teeth in optimal position with reference to the lips, both vertically as well as antero-posteriorly.
The facial characteristics of an individual are measured through anthropometry, photogrammetry, computer imaging and cephalometric radiographs. Cephalometric radiographs offer significant diagnostic information regarding the association between the dental and skeletal structures. Lateral cephalogram has been reported in the literature as an essential element of the diagnostic procedure in orthodontics. Frontal and lateral photographs of the patient correspond to another frequently used diagnostic method. Linear and angular soft tissue facial profile analysis on photographs is carried out corresponding to radiographic cephalometry.
While taking a lateral cephalometric radiograph, the patient is exposed to radiations, moreover; the bony structures overlap each other that enhances the likelihood of misreading of the measured values. By means of photogra

Current Primary Outcome: Mean values of facial profile angles and linear measurements [ Time Frame: Within one week after cephalographs and photographs have been taken. ]
Original Primary Outcome: Same as current
Current Secondary Outcome: Comparative angular and linear parameters [ Time Frame: Within two weeks after cephalographs and photographs have been taken. ]
Original Secondary Outcome: Same as current
